Say what you will but the bubble train is the most OP shit I ever seen. Did it one time just for shits and giggles and with armor of light the bladedancers coming in stood no chance. Golden guns shotguned as they tried to enter. Nova bomb might take out one or two bubbles but regrouping was easy peasy and sunsingers? Ha no chance. The fist of havoc is the best counter for it but even then just regroup and you're back in the game again.
